No distilled spirits, no drawback question. And a different set of container problems.

An MCT blend is not an alcohol extract

It is a cannabinoid preparation in a medium-chain triglyceride carrier. Which means the spirits tax provisions this property is built on do not arise.

So one of five leaves sits outside the spine

Stated plainly, because a property built on a rule should say which of its leaves the rule does not reach.

Oil changes the closure problem

An oil film on a thread makes a cap feel loose and travel further on closing. A liner that compresses once and stays compressed behaves differently with oil than with alcohol.

And it changes the dropper problem

A viscous oil draws slowly into a pipette and drains slowly out, so the dose takes longer and the last drop hangs. A wider orifice helps and a graduated pipette becomes harder to read accurately.

Oxidation replaces evaporation as the risk

An alcohol extract loses volume and strength to evaporation. An oil does not evaporate and instead oxidizes, which is a light and oxygen problem rather than a seal-tightness one.

Which argues for the colored glass

18 amber, 17 blue and 7 frosted containers out of 74, against 20 clear. This is the only cannabis shelf in the catalog with a real protective majority.

Blue is unusual and useful

17 containers, which is almost as many as amber. Cobalt blocks a different part of the spectrum and it is a deliberate look as well as a barrier.

Headspace matters less than for a concentrate

An oil in a 30 mL bottle with a dropper is being opened daily, so the headspace refreshes anyway. The protection has to come from the glass.

The capacity window is the same

10 to 120 mL, median 30. An oil blend is dosed in the same volumes as an alcohol extract even though everything else about it differs.

And the fit problems are the same

Twelve containers with no closure, 71 of 74 full case only. Those apply whatever is in the bottle.

Written from 27 CFR 17.131 and 17.132 and from the catalog as it stood on 19 October 2026. Part 17 is a drawback provision, a mechanism for recovering federal excise tax on distilled spirits used in nonbeverage products. It is a tax rule rather than a safety or packaging rule, and nothing here states whether any particular product is within its scope. Availability, quote-only and full-case figures are a single snapshot rather than a trend. The twelve 18DIN containers on this shelf have no matching closure on it.
